SASH-WEXGHT MOLD.

Application filed February 5, 1926.

My invention relates to new and useful improvements in permanent chill or molding machines employed in the production of sash weights and kindred articles, and Vobjects of the invention are the provision of a quick operating machine of great capacity7 and economy in the production of such articles.

@ther objects will hereinafter appear, and in order that the invention may be fully understood reference will now be had to the accompanying drawings, in which:

llig. l is a plan view ot the machine with portions of the table legs broken away.

Fig. 2 is a rear elevation ot the machine.

Fig. 3 is a vertical section on line 3-3 of Fig. 2.

Fig. 4 a vertical section of one ot the molds on line 4-4 oit' Fig. 2.

Referring now in detail to the various parte, 2 designates a table consisting et legs 4 and a rectangular top 6, which latter is provided at itsV ends with horizontal trunnions 8 journaled in bearings at the upper portions of the former, so that said top 6 can revolve in a vertical plane and altere nately carry the two batteries of molds mounted thereon in position to receive the molten metal and discharge the completed castings. Bolts l and l2 are employed'tor holding the table top 6 stationary during the pouring ot' the molten metal and the delivery of the castings. Said bolts l() and l2 have pin and slot connections 14 and 1G with hand levers 18 and 2() tulcrumed at 22 and 24 and held in their adjusted positions by notched segments 26 and 28, respectively.

rThe two batteries ot molds may comprise any suitable number of individual units, each battery in the present instance consisting of four units. As shown more clearly by Fig. 3, the two batteries are mounted at diagonal corners of the table top 6 and arranged in reverse position to each other, so that when the uppermost `units shown at the right are in position to receive the molten metal the lower-most units at the lett are in position to deliver the castings.

Each unit consists of lower halves or sections 30, upper halves or sections 32, and a standard 34 uniting the upper and lower rearmost sections. The lower sections 30 are connected by a hinge 34d and the lower trent section 36 is normally held in closed position by a latch 38 pivoted to the lower rear section 40 and a stud 42 fixed to said front section 86. The rear section 4() is Serial No. 86,230.

lirinly secured to the table top 6 by suitable means, bolts 44 being shown `for that purpose.l The bore ot' the lower sections 30 is provided near its lower portion with studs 44a which abut each other as shown by Fig.

4 when said halves are closed and form the eye in each sash weight. Said bore also has lugs 46 to support a tube 48 which becomes a portion ot the finished sash weight. Said tube 48 may consist of a section ot wrought iron pipe or sheet metal as preferred.

ka gate 58, and that portion of the bore in the front section 56 communicates with a recess provided tor the reception ot a removable plug G2 bearing a number or other identiiiying symbol to be impressed :in the cash ing.v The latches 38 and 50 tit the respective `studs 42 and 54 friction tight, so that when the molds are turned to an inverted position preparatory to delivering the castings, said latches will not become accidently disengaged from the respective studs and permit premature opening of the molds.

The standard 34 is removably mounted in sockets 64 and 66 in the lower rear section 4() and the upper rear section 52, but normally secured in said sockets by set screws 68 and 70, respectively. The set screw 70 enables the upper section 32 to be adjusted to different elevations tor different weigl'its and lengths of sash weights and the standard 34 is graduated in order that said upper halves 32 may be quickly and accurately adjusted to the desired elevation.

82 designates a shield secured to the table legs 4 to direct any castings into the buggy 80 which may become accidently delivered from the molds when rotated from theirk uppermost to their lowerinost position.

i The operation vbriefly stated, is as follows: rihe lower sections 30 of the units which happen to be uppermost on the tables are closed and secured in closed position by engaging the latches 38 over the respective studs 42,

zitter which the tubes 48 are inserted in the A open ends ot the bores ot said sections 30. Scrap in the form o t' old bolts, rods, etc., is then dropped into the tubes 48, after which the upper sections 32 are closed around the upper ends ol' ,nid tubes 48 and secured by Cil engaging the latches 50 over the respective studs 5l. Y The molten metal is then poured into the molds through the respective gates 5S, after which the bolts l() and l2 are withdrawn from the respective recesses in the table top (3 and the saine is turned a half revolution to carry the iilled molds downwardly to deliver the castings and the empty molds upwardly to receive a supply of tubes 48 and molten metal. After the table top C has been turned a half revolution as stated, the latches 3S and 50 of the lowermost units are disengaged from the studs 49. and 54, respectively, and the molds are opened to deliver the castings to a suitable conveyor such as a buggy SO, provided for the purpose of conducting the hot sash weights to a dump where they are allowed to cool.

From the foregoing description it is apparent that I above provided a molding machine embodying the advantages above pointed out, and while I have shown and described the preferred construction, combination and arrangement of parts I reserve all rights to such modifications thereof as properly fall within the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In ay machine of the character f described, a mold consisting of lower sections, upper sections, a standard supported by one of the lower sections, and means for securing one of the upper sections at different elevations upon saidy standard.

2. In a machine of the character described, a mold consisting of two lower sections, two

1,649 ica upper sections, sockets on one of the lower and upper sections, a graduated standard fitting within said sockets, and means carried by the upper socket for securing the upper sections at ditl'erent elevations upon said standard.

f3. In a machine of the character described, a mold consisting of two lower sections hinged together, latch means for holding said sections in closed position, two upper sections hinged together, latch means for securing said upper sections in closed position, graduated means upon which the upper sections are adjustably supported above the lower sections, and a tube ar anged to fit within the lower and upper sections.

4. In a rectangular machine of the character described, a table having a top rotatable in a vertical plane, and reversely disposed molds secured to diagonal corners of said top to rotate therewith.

5. In a machine of the character described, a table having a rotatable top, reversely disposed molds secured to diagonal portions of said top, bolts for holding said table top stationary, and levers for'actuating said bolts.

ti. In a machine of the character described, a table having a top, horizontal trunnions mounted upon the table and connected to opposite sides of said top to enable the latter to rotate in a vertical plane, reversely disposed molds secured to diagonal portions of said top to rotate therewith, and a conveyer spaced beneath the table top and into which the contents of the molds are discharged.

In testimony whereof I alx my signature.

EDIVARD GRANT.
